Data can sometimes reveal what an expert spent years to learn and sometimes much more. So when used as an exploratory tool, it has good benefits. And to a degree, it can predict future outcomes to a good degree if we have a great theory about the target domain that explains almost everything. Unfortunately, this tempts people to try using data in domains where their expertise doesn't justify their predictions and then it becomes a gamble where the winners get a lot of publicity.
